I send myself links to prescription drugs sites, mostly for Viagra. I've Googled all over to try to find a way to stop it, but no luck. You can't block yourself from yourself. It sucks because they send me ten or more everyday. All I can do is delete them.

.... once that is done, well there's nothing much you can do. This is one way that spammers try to "hide" their trail - by sending you an email a spam from "you". They may also send spam as you to other people, but you won't know until someone either sends you a nasty reply, or you start getting "bounced back" emails.

Tim Gossling is getting spam that claims it has been sent from his own email address

I've just had a spam email in which the "from" address was the same as the "to" address, ie mine. The subject was something like Error: returned email. Is this a new wheeze to get round spam filters?

Tim Gossling
Yes. Internet email systems don't actually use the To: and From: addresses, which can be forged to say anything. The recipient (you) is identified in the headers that are created when the mail software sends the email to the mail server. Mail headers are hard to read, and nowadays, most mail software hides them. The trick works because curiosity may make people more likely to read a message they appear to have sent themselves. Also, you can't really blacklist your own address, though *content-based blockers should still catch this type of spam. But I wouldn't worry about it unless you have a copy of the same email in your Sent folder.Why do I seem to be sending spam to myself? | Technology | guardian.co.uk

So it's just a spoof. You aren't sending spam, it's just making it look like you sent it to yourself.

The bolded is where the email came from, and I can't find much on the IP

The italics is from an internal server and it shows when the email was received and to sent out. This IP comes from Orlando, so I'm guessing it's the IP addy to your email provider, I'm not completely sure.

The IP originates in Orlando, Florida. It's amazing what you can find out if you just Google an IP. There's other stuff there about bots and browsers which I don't understand being the technotard that I am. What you can actually DO if your puter is infected is another matter. Probably not much. You might have to think about getting yourself a new, more secure email addy. Gmail is good.
